Test Mnemonic: SE S
Methodology: Inductively Coupled Plasma/Mass Spectrometry

Performed: Mon-Sat

Reported: 1-3 days

Specimen Required:  
Collect: One 6 mL royal blue (no additive), or royal blue EDTA.

Transport: 2 mL serum or plasma at 20-25°C. (Min: 0.5 mL) Submit specimen in an ARUP Trace Element-Free Transport Tube (ARUP supply #43116).

Pediatric Collection/Transport: 0.5 mL serum or plasma at 20-25°C. Submit specimen in an ARUP Trace Element-Free Transport Tube (ARUP supply #43116).

Remarks: Centrifuge and pour off serum or plasma into an ARUP Trace Element-Free Transport Tube ASAP. Do not allow serum or plasma to remain on cells.

Unacceptable Conditions: Separator tubes and samples that are not separated from the red cells or clot.

Stability: If the specimen is drawn and stored in the appropriate container, the trace element values do not change with time.

Reference Interval:
23-190 µg/L

Note:
Elevated results from noncertified trace element-free tubes may be due to contamination.  Elevated concentrations of trace elements in serum should be confirmed with a second specimen collected in a trace element-free tube, such as royal blue sterile tube (no additive).

CPT Code(s):
